The company also undertakes cryogenic insulation jobs.  It has specially designed Portable Plants to carry out ON-SITE jobs.  At present the company owns 7 such Portable Plants. Large jobs have been executed in a short period of time and the technical team has acquired a high degree of expertise in performing these jobs with required high precision working.


Perlite, in its natural state, is a volcanic siliceous rock. When crushed and heated up to a temperature of approximately 930°C., it pops like “popcorn” expanding from four to twenty times its original volume.The expansion of Perlite takes place due to the presence of 2 to 6 per cent combined water in Perlite Ore. 


Raw Perlite is a siliceous volcanic glass, containing 2 to 5 per cent combined water. When rapidly heated to the proper temperature, the volatilization of the water, coincident with the softening of the glass, causes the Perlite to suddenly expand or “pop” into light weight cellular particles or “bubbles”. 


The insulation is covered using different materials depending on the application, environment and aesthetic value desired by the customer.  Large projects on a turnkey basis are taken up which includes providing cold insulation using PUF and other materials.
